I have two laptops, I’ll call them laptop 1 and laptop 2.

Laptop 1 is my gaming laptop, and laptop 2 is a very low-spec one that I use as a jellyfin server. Here’s the neofetch result for both of them:

Laptop 1

Laptop 2

The problem

On both of them, I copied a 5GB folder from the laptop to my 3.0 usb flash drive, I used this rsync command on each:

rsync -a --progress folder_path destination_folder_path

Laptop Average transfer speed
Laptop 1 9MB/s
Laptop 2 45MB/s

How is this possible? The Laptop 1 is way superior than laptop 2. The laptop 1 has an nvme SSD while laptop 2 has an old 320GB HDD, yet the transfer speed difference is insane.

Does KDE affect the folder copying somehow? If I copy a file on the same SSD on laptop 1, the speed reaches more than 400MB/s.

What is going on here?

    Oh yeah, Baloo can do wierd things. Shouldn’t be related tho.

    I’m down to help. You should investigate whether the USB standard being used is different, though both those speeds should be possible whether it’s usb 3 or 2.

    I assume the difference is consistent? Same files, same drive, same thing every time?

    What’s it rated for? If you use something like hdparm to benchmark it on each laptop, are the results wildly different?

    The gnome disks tool also has drive benchmarking if you prefer a GUI.
